The M50 DSS picks up where the legendary M1 Momentum leaves off. It is still ruggedly stylish and incredibly reliable, but even more so with a 10-year battery and almost unheard of 6-year warranty. If you’re serious about diving, then you owe it to yourself to take a closer look.

The meticulously finished case is machined from a block of high-grade 316L stainless steel, and utilizes a scratch-resistant sapphire crystal to let it stand up to rough handling. The calendar date displayed at the 3 o’clock position, is easy to read with the over-size date magnifier made into the crystal.
It has a patented “Blackout Superluminous” dial and hands providing clarity in the dark, plus large hands with numerals and hour markers for easy reading. The dial comes in several choices of color including black, blue, and white, but the blue is particularly compelling.

With a unidirectional ratcheting bezel, and screw-down crown, this watch is ISO 2281 compliant, and rated water-resistant to a depth of 500 meters or 1650 feet. It comes with a durable black rubber strap.
It also features a Japanese quartz movement and a 10-year battery life. All this is backed by a 6-year manufacturers warranty.
St. Moritz is a leader in specialty watches for water-sports, and a recognized as a leading manufacturer of fine diving watches.
Here’s just a brief recap of what makes the all-new Momentum M50-DSS stand out above the ordinary:
- Solid 316L stainless steel case
- 500M / 1650FT Water-resistance (ISO 2281 compliant)

The legendary M1 Momentum
is very much a serious dive watch. Considered ground-breaking when first introduced by St. Moritz Watch Corp., it remains a leader in terms of its combination of rugged style and reliable performance, all at a reasonable price.
The case is made of solid 316L stainless steel, and comes with either a heat-tempered mineral crystal, or a scratch-resistant sapphire crystal.
It has a Superluminous dial and hands providing clarity in the dark, plus large hands with numerals and hour markers for easy reading. There are several choices of dial color including black, blue, orange, yellow, white, and lime. The calendar date is displayed at the 3 o’clock position.
The M1 can be had in a large (43mm x 12mm) men’s size or the smaller (32mm x 10mm) for women. You can also get the Special Edition M1 PRO version, which has the well-recognized, red & white, “diver down” flag discretely placed on the watch-face.
With a unidirectional ratcheting bezel, and screw-down crown, this watch is rated to a depth of 200 meters or 660 feet. It features a Japanese quartz movement and long battery life.
There are two options for the strap. Either a black rubber band with a latching clasp, or a nylon band that uses a Velcro closure.
I don’t recommend the Velcro as it caused me the loss of my M1 that I’d had for many years. What happened was that the hook and loop of the Velcro gradually wore away at the tip of the band until it curled up a bit. While diving last year I must’ve somehow brushed against it enough to let it slide out during one of our dives, and it disappeared forever.
